Great pictures of the bolt in your previous post. The NOV 2005 edition of the "American Rifleman" says on pg 112. "The handle is an investment casting, swaged, press fit, and then brazed to the rear of the bolt body.....". If the handle was splined to fit the teeth of the body and brazed it probably would last forever. Can't tell from the pics if there was any brazing. Also wonder if a machine shop could run these two pieces through a collet and crimp them. Kind of like a giant Lee "factory crimp die". In all seriousness, Mossberg should do a recall of all ATR (and 4x4?) bolts to check them out for defects. -AimHigh
